Alphabet starts collecting health info to better predict disease

IBM's Watson supercomputer will play Jeopardy! on these dates

What are February 14th, 15th, and 16th? We've known it was going to happen for a while, but now we know when to set our DVRs. A rack of servers -- soaked with natural-language processing, armed with a battalion of esoteric pop culture knowledge, and "represented by a round avatar" -- will face off against Jeopardy! millionaires Ken Jennings and Brad Rutter (both profiled in video after the break) for three days starting on Valentine's Day 2011. We're also hearing that Watson will sign autographs after it's done decimating its opponents. It will then donate all its winnings to charity and spend the rest of its natural life dodging paparazzi on an undisclosed beach in the South Pacific.
